Title: Operation of pulsed electrostatic precipitator - by combining pulsed and steady DC voltages to avoid adverse sparking conditions
Inventor: FELDMAN PAUL LOUIS
IPC: B03C3/68
Filed: 1980-02-07
Abstract: Multisection precipitator having at least three sections, each having 0.109-0.250 in. dia. wire electrodes spaced 3 1/2-5 1/2 ins. apart, and collecting electrodes spaced 9 ins. apart, the inter electrode spacing being 4 1/2 ins. and the collecting plate areas in each section >=8200 ft.2, is operated by (a) applying a DC base voltage of 30-50 kV between discharge and collection electrodes such that the value is near but just below the corona starting voltage and the resultant electric field is 3.0-7.5 kV/in.; (b) applying in parallel to the discharge electrodes of one or both of the first two sections, short pulses of 50-80kV, of the same polarity as the base DC voltage, at 80-200 pulses per second, such that the pulse plus base voltage is above normal DC breakdown value; (c) setting the pulse voltages to have a fast rise time is not >200 ns and a short decay time, and a pulse width of 250-1500 ns. to avoid excessive sparking; (d) adjusting the DC base voltage in coordination with adjustment of the applied voltage pulses to vary the charging and collecting fields independently and maintain an average current through the collected dust layer at or just below that value which would cause electrical breakdown of the dust layer. Problems of handling difficult dusts and their inherently deficient particle charging and collecting fields are overcome. The charging and collecting fields may be varied independently so that each may be adjusted to a level that results in optimum precipitator performance.

Title: Remote control for electronic flash units - has IR transmitter and receiver and threshold signal activated by integrating circuit
Inventor: DIETRICH ROLF
IPC: G03B15/03
Filed: 1980-05-02
Abstract: The flash gun control circuit (II) is a self-contained unit and the master unit (I) is linked to the flash gun by two sets of IR beams. One beam initiates the flash discharge and the second beam triggers the flash quenching control, in response to a light monitoring circuit on the master unit. A first LED (2) on the master unit provides the first IR beam at a first frequency. This is identified by a diode (24) on the flash gun to start the flash discharge. The light output from the flash gun is monitored by a detector (15) on the master unit and when a set amount of light has been monitored a second LED (4) provides a second IR frequency. This acts on a second detector (33) on the flash gun and operates the quenching thyristor (19) to terminate the flash. No wire connections are required.

Title: Process for improving the heat economy of a groundwood pulp production process
Inventor: AARIO MATTI
IPC: D21B1/24
Filed: 1981-05-26
Abstract: In the process, wood is ground by means of a rotating grinding element (2) in a pressurised grinding chamber (3) and warm spray water (6) is sprayed into the grinding chamber. The groundwood pulp obtained is thickened by dewatering and the water removed is reused as spray water (6) for the grinding chamber. Simultaneously to the thickening, the groundwood pulp is cooled by spraying with cooling water (E) whose temperature is lower than that of the groundwood pulp. At least one part (E1) of this cooling water is stored and added to the water (F) removed from the groundwood pulp as replacement water for the spray water which is lost in the grinding process. By this means, the heat energy produced in the groundwood pulp by the grinding process is utilised for heating the replacement water, as a result of which the need to use external energy for this heating can be avoided. <IMAGE>
